Host name and dhcp question

I have a network at home behind an IPcop firewall. Most of my
computers have static IP's. However I would like to move to dhcp. I
have set up my IPCop firewall to run a dhcp. I also have just
installed Ubuto Linux on one of my computers. The computer's name is
NE. I have this computer access the IPCop's dhcp to get it's IP
address. This works fine. But the host name of the computer NE does
not show up in IPCop. Also I can not ping this computer from my other
computers by just giving the host name. Ping does work if I use the
IP address of NE.

The question:
How do I use dhcp on my local network and still connect to the other
computers by just using the host names?

What am I missing? What man pages do I need to read?

Thank you for your time

You need to edit your file:

/etc/dhcp3/dhclient.conf

so that it contains the line:

send host-name "NE";

Then your firewall will know your computer by name.

Why would you want to do that? It seems silly, not just for the reasons you
your self demonstrate below.

You need a DNS server-- is IPcop also a dns server? Or did you simply put
the names into /etc/hosts?
Ie, there needs to be some machine or the /etc/hosts file which translates
names to IP addresses.

Your firewall may, but is it acting as a DNS server as well? That is not
usually the role of firewalls.

Thank you Robert. I can now get to NE by using NE name.

Yes, it does. It's a GNU/Linux distribution that sets up PCs as secure
firewalls. See: <http://www.ipcop.org>
